Title: Vertical axis wind turbine with feathering vanes
Inventor: MEWBURN-CROOK ANTHONY JAMES SE
IPC: F03D3/04
Filed: 1983-03-15
Abstract: Each of the vertically extending blades 10 of the turbine 9 is pivotally mounted about a vertical axis passing through the blade and a torsion bar 11 for automatically restraining pivotal movement of the blade about its vertical axis is provided. The wind generator has good self starting characteristics and, as the velocity of the wind increases, each turbine blade 10 will pivot against its associated restraining torsion bar 11 from an initial position to a normal running position (at an angle of 0 to +5 DEG  of the tangent). If the velocity of the wind increases above a maximum acceptable value, each blade 10 will pivot smoothly from the normal running position to a "feathering" position thereby ensuring that, as the velocity of the wind exceeds the maximum acceptable value, the rotational speed of the turbine 9 is not increased to an undesirable extent. <IMAGE>

Title: A.C. lift control system
Inventor: HATAKEYAMA TAKANOBU
IPC: H02P21/36
Filed: 1983-04-06
Abstract: In an AC lift control system in which the voltage and frequency applied from an inverter unit (3) to an induction motor (4) driving a lift car (9) are controlled to control the operation of the car in a normal operation mode, a battery (18) is connected to the DC input terminals of the inverter unit for use in an emergency such as sudden service interruption, and a switching signal generator (16) operating in an emergency operation mode generates a switching signal for controlling the output of the inverter unit (3) in such a manner that the number of switching is smaller than that in the normal operation mode and the duty factor per unit switching is larger than that in the normal operation mode. Therefore, a battery (18) of low voltage and small size can be used. <IMAGE>

Title: Magnetic motors
Inventor: CROOKES WILLIAM MARTIN
IPC: H02K25/00
Filed: 1983-08-30
Abstract: An electric motor comprises a stator 10 having two acurate permanent magnets 12 and 13 arranged in an annular configuration but with gaps 14 and 15 between the ends thereof. The magnets are magnetised with one pole on the arcuate outer surface and with the other pole on the arcuate inner surface. Pole pieces 16 and 17 are located in the gaps 14 and 15 respectively, each pole piece having a field coil 20 and 21 respectively associated therewith. A rotor 11 is mounted concentrically with the stator 10 and carries a pair of permanent magnets each disposed with one radial face magnetized with one polarity. The rotor shaft carries a switching arrangement for electric current from a source 30 to the coils 20 and 21. On rotation of the rotor, each time one of its bar magnets approaches a position of suitable equilibrium adjacent a gap between the stator magnets 12 and 13, the current is supplied to the coils 20 and 21 so as magnetically to plug both gaps and hence render uniform the magnetic field in the region of the gap. After the rotor magnets have passed the gaps, the current supplied is discontinued and the rotor may continue to turn towards the next gap. <IMAGE>

Patent GB-2144772-A (GB)
Title: Magnetron sputter coating source for both magnetic and nonmagnetic target materials
Inventor: BOYS DONALD REX
IPC: H01J37/34
Filed: 1984-07-16
Abstract: A novel magnetron sputter coating source is disclosed which may be used efficiently and effectively with sputter target materials having properties which range from nonmagnetic to highly ferromagnetic. Use of an electromagnetic coil with a widely adjustable energizing current, rather than permanent magnets, allows a wide range of magnetic properties to be accommodated. Electrical impedance of the glow discharge is readily controlled using the current flow through the electromagnetic coil, allowing, for example, operation at desired values of voltage and current throughout the life of the sputter target. In addition, a momentary increase in electromagnet coil current can be used to achieve ignition of the glow discharge at a desired sputter gas operating pressure which is below the sputter gas pressure at which the flow discharge can normally be readily ignited. Also, use of the electromagnetic coil permits an easy conversion of the magnetron sputter coating source to a nonmagnetic diode apparatus. In one embodiment (Fig. 1) the coating source comprises anodes (10,11), a cathode (13) which also serves as sputter target, a magnetic circuit comprising an electromagnetic coil (20) coaxially wound round a central polepiece (27), and an annular polepiece (25) coaxially surrounding said coil, said polepieces being configured to form coplanar end surfaces having annular pole faces spaced apart to form a planar annular nonmagnetic gap bridged by the sputter target (13). The use of a Hall probe positioned adjacent and below the sputter target near the region of maximum erosion is disclosed. The Hall probe voltage, which is proportional to the magnetic field intensity at the Hall probe position, may be measured throughout sputter target life to provide an independent means of assessing the approach to end of useful life. A novel sputter target cooling means is disclosed in which a water chamber below the sputter target is divided into inlet and outlet portions by a septum. The flow of water through a narrow gap between the septum and the sputter target leads to highly effective heat transfer, which is also highly uniform along the peripheral path of intense heating of the sputter target. <IMAGE>

Title: Scanning radiant energy
Inventor: ABEL KONRAD
IPC: H04N3/09
Filed: 1984-12-21
Abstract: A process and apparatus for scanning, for example, infra-red radiant energy uses a horizontal detector line and two scanning mirrors for sweeping an image over this detector line. The first mirror sweeps in the vertical direction during the TV field time. Using the second scanning mirror, the radiant energy is in addition moved over the detector line in a horizontal direction, the forward and return sweeps corresponding in each case to one line duration and the amplitude of deflection corresponding to the width of only a few individual detector elements. Eight line rasters LR are picked up during each horizontal forward and return sweep and stored in a shift register. The line rasters are read out in a pre-determined sequence so that they become interlaced to form a TV-compatible video signal. The multiple rasters of a line, spatially displaced from one another, enable aliasing effects to be avoided up to local frequencies corresponding to the limit of resolution determined by the dimensions of the individual detector elements. This can be achieved with only one quarter of the number of individual detectors elements per line which would be required without the additional horizontal deflection.   <IMAGE>
